Ardelia Guide and Best Builds
Ardelia Guide & Best Builds
Welcome to our Ardelia build guide for Arknights: Endfield. Ardelia is a 6-star Arts Unit Supporter Character available in Arknights: Endfield who utilizes the Nature element.
In our Ardelia guide, we'll cover everything you need to know to get the most out of your Ardelia, from building the best Gear and Weapons, to important stat priorities and combos.
Ardelia's Best Weapons
Dreams of the Starry Beach
- Intellect +156 (9/9)
- Treatment Bonus +46.43% (9/9)
Infliction: Tidal Murmurs (4/9):
Secondary attribute +25.6%.
After the wielder consumes Corrosion, target enemy suffers Arts DMG Taken +16% for 25s.
Effects of the same name cannot stack.
Monaihe
- Willpower +124 (9/9)
- Ultimate Gain Efficiency +37.14% (9/9)
Inspiring: Mortise-and-Tenon Analysis (9/9):
Main Attribute +14%.
Arts Intensity +70.
Ardelia's Best Essences
Essences are one of the repeatedly farmable ways to further boost the damage of your Ardelia. Which area and essence you will want to farm will depend on the weapon you are playing, as not all Essences are compatible with every weapon. Essences will increase the stats of your weapon, as well as enhance the passive effect it provides.
- Dreams of the Starry Beach: Intellect Boost, Treatment Efficiency Boost, and Infliction, farmable in Originium Lodespring and Power Plateau.
- Monaihe: Will Boost, Ultimate Gain Efficiency, and Inspiring, farmable in The Hub and Wuling City.
Essences can be further upgraded through a system called Etching which will be a long-term investment due to how much Sanity it takes to fully max out a weapon. You may therefore want to farm and Etch Essences for a signature weapon already if you plan on getting it in the near-future, even if you do not have the weapon yet. A simple +1/+1/+1 Essence for a temporary weapon like Monaihe will be good enough until you can get your hands on Ardelia's Dreams of the Starry Beach.

Leveling Gear for Ardelia
While the above gear set is the optimal choice, it might take you some time before you will be able to craft it. Below are some of the more early and mid-game sets that we recommend until you've reached the pinnacle of craftsmanship.
Mordvolt Resistant
When the wearer's HP is below 50%, Treatment Effect +30%.
- Body: Tide Surge Offpiece — Will, Intellect, HP
- Hand: Mordvolt Resistant Set — Will, Intellect, Heal Output

- Kit 2: Mordvolt Resistant Set — Will, Heal Output
Ardelia's Skill Priority
Almost all of the combos with other Operators rely on Ardelia casting her Battle Skill, which is why you should absolutely prioritize it over anything else. Her Combo Skill and Ultimate are both useful as well, while her Basic Attack can be left alone until you can afford to spend resources on leveling it up.
How to Play Ardelia
What might look like a difficult kit at first, is actually quite simple. Ardelia is built around providing HP Treatment to her teammates by spawning zones of Healing, which you can stepped into with the Controlled Operator to either heal themselves, or the most injured party member, if the Controlled Operator is at full health.
Simultaneously you will want Ardelia to buff the team, by applying Corrosion and then consuming it with her Battle Skill. While normally this would require the set up of two other Operators, Ardelia can do it almost all by herself. Her Combo Skill applies a temporary Corrosion effect already, which can be triggered by hitting any enemy that isn't currently inflicted with any Arts Inflictions or statuses with a Final Strike of your Controlled Operator.
You will therefore want to be careful with using Ardelia's skill, until the enemy is stripped of their debuffs, to then trigger her Combo Skill with a Final Strike, before consuming the freshly applied Corrosion with her Battle Skill. The enemy will now be sitting there with a Physical and Arts Susceptibility, while the rest of Ardelia's team can take them apart.
